A term of irony used for a very self-serving mother with very little inherent nurturing instinct and often a victim of psychosis and/or bipolar disorder. Her ugly and abusive behaviors often include but are not limited to: name calling, tyrannical micromanaging, violent rages, insensitivity, blaming her mistakes on everyone else, extreme vanity, envy of her childrens' talents disguised as "constructive" criticism, and a propensity towards often having a very phony and pleasant public facade. Joan Crawford was the prime example of such a mother.
